Protective Window / Protective Lens – 40×3 mm | Up to 15KW
The Protective Window / Protective Lens – 40×3 mm is a high-quality optical protection component designed for use with compatible high-power fiber laser cutting heads and laser cutting machines with power capacity of up to 15KW. It serves as a protective barrier between the cutting area and the sensitive internal optical components of the laser cutting head.
During laser cutting operations, metal spatter, smoke, dust, fumes, and cutting debris can reach the cutting head and contaminate the internal optics. This protective lens helps shield the focusing and other optical components from these contaminants, supporting reliable laser beam transmission and consistent cutting performance.
